About parents not wanting to become grapndparents - I grew up with only one set of grandparents, both of whom lived to be very, very, very old, especially grandmother, who also never liked her daughter-in-law (my mother). So when my eldest sister got pregnant with the first baby in the family since me, Mom didn't want to be called Grandmother, since the only person by that name had been such a horrible person. So we started calling her Aunt Mom instead, and it's stuck. We like it that way.

We are also in the habit of calling all pregnancies Clark(e) - with an e for a girl and without one for a boy.
